Hello. Recently I bought a Dreambook W7. But I have a big problem. I can see the name of Carrier Network but next to it I always get the message "No Service" And the intensity signal icon is always with a "X" Example: (No service) - TELCEL (by the way here in Mexico "TELCEL" is the principal carrier) I can not make phone calls, no 3G. I have tried with *#*#4636#*#* phone information. GSM Service: Emergency calls only GPRS: Disconnected GSM Disconnects: DATA. State: DcInactiveState fails because No error I've changed CDMA, GSM/CDMA etc. I have tried to search Available networks too. Select automatically. Nothing. System Information: Android: 2.2 BaseBand version: 1575B07SIM526E Build: HD105 Any help... Welcome! regards!
